Isopogon longifolius is a small shrub in the family Proteaceae that is endemic to the southwest of Western Australia.

Description[]

Isopogon longifolius is a small shrub (1-2.5 m high) with smooth branchlets. The smooth, flat leaves are alternate, and 85–220 mm long, and 6–30 mm wide. They are widest above the middle, and have smooth edges. The cream/yellow inflorescence is not sticky. The hairy perianth 13–15 mm long. The pistil is 15–20 mm long and the pollen presenter is spindle-shaped and smooth (2.5-3.5 mm long). The cone has deciduous scales, and is 24–28 mm long. It flowers in January, October, November or December.[4]

Taxonomy[]

The species was first formally described by botanist Robert Brown in Transactions of the Linnean Society of London in 1810.[2] In 1891, German botanist Otto Kuntze published Revisio generum plantarum, his response to what he perceived as a lack of method in existing nomenclatural practice.[5] Because Isopogon was based on Isopogon anemonifolius,[6] and that species had already been placed by Richard Salisbury in the segregate genus Atylus in 1807,[7] Kuntze revived the latter genus on the grounds of priority, and made the new combination Atylus longifolius for this species.[8] However, Kuntze's revisionary program was not accepted by the majority of botanists.[5] Ultimately, the genus Isopogon was nomenclaturally conserved over Atylus by the International Botanical Congress of 1905.[9]

The accepted description for Isopogon linearis is that of Foreman (1995) in Flora of Australia.[2][10]
